Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a heat dissipation device for a fire smoke exhaust fan. Background Technology
[0002] Fire exhaust fans are crucial equipment in fire rescue operations, playing a vital role in removing dense smoke from fire scenes and creating a favorable environment for rescue work. In actual operation, fire exhaust fans run under high load for extended periods, generating significant heat in critical components such as the motor. Currently available fire exhaust fans suffer from several shortcomings in their heat dissipation methods. For example, natural cooling is inefficient and fails to effectively reduce equipment temperature quickly, leading to overheating and fan malfunction, which in turn hinders the smooth progress of fire rescue operations.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When the exhaust fan body works for a long time, the temperature of the exhaust fan body continues to rise. The high temperature will affect the performance of the motor of the exhaust fan body. For example, the output power of the motor may decrease, resulting in insufficient smoke exhaust volume and air pressure, which cannot meet the design requirements of fire smoke exhaust and affect the smoke exhaust effect. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of preventing the exhaust fan body from working for a long time, causing the temperature of the exhaust fan body to rise continuously, and the high temperature will affect the performance of the motor of the exhaust fan body. To this end, we propose a heat dissipation device for fire smoke exhaust fan.
[0005] To achieve the above objectives, this application adopts the following technical solution: a heat dissipation device for a fire-fighting smoke exhaust fan, comprising an exhaust fan body, two support legs fixedly connected to the arc surface of the exhaust fan body, a water-cooling device provided on the arc surface of the exhaust fan body, the water-cooling device comprising two water tanks, both water tanks being fixedly connected to the surface of the exhaust fan body, a plurality of water-cooling pipes fixedly connected to the arc surface of the exhaust fan body, a plurality of flow pipes fixedly connected to the surface of the exhaust fan body, one end of two of the water-cooling pipes being fixedly connected to the flow pipes, a filter screen being fixedly connected to the inner surface of the water tanks, and a plug being slidably connected to the surface of the water-cooling pipes.
[0006] Preferably, a fixing block is fixedly connected to the surface of the water tank, and rotating rods are fixedly connected to both sides of the fixing block. A protective plate is rotatably connected to one end of the two rotating rods that are far apart from each other. An L-shaped plate is fixedly connected to one side of the water tank, and a bolt is inserted into the internal thread of the L-shaped plate. A square plate is fixedly connected to the surface of the protective plate.
[0007] Preferably, the arc surface of the rotating rod is fitted with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the protective plate and the fixing block.
[0008] Preferably, an absorbent pad is fixedly connected to the surface of the protective plate, and the size of the absorbent pad is adapted to the size of the protective plate.
[0009] Preferably, a wire fixing device is provided on the side of the two support legs that are close to each other. The wire fixing device includes a shaped plate, which is fixedly connected to the side of the two support legs that are close to each other. Two wire fixing rods are slidably connected inside the shaped plate. A fixing rod is fixedly connected to the arc surface of the wire fixing rod. A single-hole plate is fixedly connected to one end of the fixing rod. An insert rod is slidably inserted into the single-hole plate. The arc surface of the insert rod is slidably connected to the shaped plate.
[0010] Preferably, a spring is fitted onto the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to the single-hole plate and the insertion rod, respectively.
[0011] Preferably, the arc surface of the insertion rod is fixedly connected to two arc-shaped plates, and the surface of the arc-shaped plates is in contact with the irregular-shaped plates.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, by setting up a water cooling device, the temperature of the exhaust fan body is reduced, avoiding the exhaust fan body from working for a long time and the temperature of the exhaust fan body continuously rising. High temperature will affect the performance of the exhaust fan motor, such as the output power of the motor may decrease, resulting in insufficient smoke exhaust volume and air pressure, failing to meet the design requirements of fire smoke exhaust, and affecting the smoke exhaust effect. This improves the practicality of the device.
[0014] In this invention, by setting up a wire fixing device, the connecting wire of the exhaust fan body is effectively wrapped and fixed, preventing the connecting wire from shaking or being dragged around due to lack of fixation during the movement of the exhaust fan body. This could lead to frequent friction, snagging, or even pulling of the connecting wire with the ground, other equipment, or sharp objects, which could easily cause damage to the outer sheath of the connecting wire and breakage of the internal wire core, resulting in short circuits, leakage, and other circuit faults, thus improving the reliability of the device.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0025] Reference Figure 1As shown, this utility model provides a technical solution: a heat dissipation device for a fire-fighting smoke exhaust fan, including a fan body 1. Two support legs 2 are fixedly connected to the arc surface of the fan body 1. A water-cooling device 3 is provided on the arc surface of the fan body 1. By setting the water-cooling device 3, the temperature of the fan body 1 is reduced, preventing the temperature of the fan body 1 from rising continuously during long-term operation. High temperature will affect the performance of the motor of the fan body 1, such as the output power of the motor may decrease, resulting in insufficient smoke exhaust air volume and air pressure, which cannot meet the design requirements of fire-fighting smoke exhaust. To address the issue of smoke extraction efficiency, the device's practicality is enhanced by installing a wire fixing device 4 on the side of each of the two support legs 2 that is close to each other. By installing the wire fixing device 4, the connecting wire of the exhaust fan body 1 is wrapped and fixed, preventing the connecting wire from shaking or being dragged around during the movement of the exhaust fan body 1 due to lack of fixation. This could lead to frequent friction, snagging, or even pulling of the connecting wire with the ground, other equipment, or sharp objects, which could easily cause damage to the outer sheath of the connecting wire, breakage of the internal wire core, and short circuit, leakage, and other circuit faults, thus improving the reliability of the device.
[0026] The specific setup and function of its water cooling device 3 and wire fixing device 4 will be explained below.
[0027] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the water-cooling device 3 includes two water tanks 301, both of which are fixedly connected to the surface of the exhaust fan body 1. Several water-cooling pipes 302 are fixedly connected to the arc surface of the exhaust fan body 1, and several flow pipes 303 are fixedly connected to the surface of the exhaust fan body 1. One end of each of the two water-cooling pipes 302 is fixedly connected to a flow pipe 303. A filter screen 313 is fixedly connected to the inner surface of the water tank 301. A plug 304 is slidably connected to the surface of each water-cooling pipe 302. A fixing block 305 is fixedly connected to the surface of the water tank 301. Rotating rods 306 are fixedly connected to both sides of the fixing block 305. A protective plate 307 is rotatably connected to the ends of the two rotating rods 306 that are far apart from each other. An L-shaped plate 308 is fixedly connected to one side of the water tank 301. Bolts 309 are threaded into the L-shaped plate 308. A square plate 310 is fixedly connected to the surface of the protective plate 307, achieving the effect of protecting the filter screen 313 and preventing… When the exhaust fan body 1 is not in operation, the filter screen 313 is exposed to the air for a long time, causing dust to cover the surface of the filter screen 313, resulting in a significant reduction in the filtration effect. The arc surface of the rotating rod 306 is fitted with a torsion spring 311. The two ends of the torsion spring 311 are fixedly connected to the protective plate 307 and the fixing block 305 respectively, achieving the effect of automatically opening the protective plate 307. This facilitates the operation of the water tank 301 by the staff, reducing the number of operation steps and improving the work efficiency. An absorbent pad 312 is fixedly connected to the surface of the protective plate 307. The size of the absorbent pad 312 is adapted to the size of the protective plate 307, achieving the effect of absorbing the collision force between the protective plate 307 and the water tank 301. The absorbent pad 312 can effectively buffer the collision force when the protective plate 307 and the water tank 301 are closed or opened, reducing the wear and noise caused by hard contact between the two.
[0028] Reference Figure 5 , Figure 6 and Figure 7As shown, specifically, the cable fixing device 4 includes a shaped plate 41, which is fixedly connected to the two support legs 2 on their adjacent sides. Two cable fixing rods 42 are slidably connected inside the shaped plate 41. A fixing rod 43 is fixedly connected to the arc surface of the cable fixing rod 42. A single-hole plate 44 is fixedly connected to one end of the fixing rod 43. An insert rod 45 is slidably inserted into the single-hole plate 44. The arc surface of the insert rod 45 is slidably connected to the shaped plate 41. A spring 46 is sleeved on the arc surface of the insert rod 45. Both ends of the spring 46 are fixedly connected to the single-hole plate 44 and the insert rod 45, respectively, thereby improving the stability of the insert rod 45 and reducing the impact of movement of the exhaust fan body 1 on the insert rod 45. The process of bumping and shaking can cause loosening and detachment, but the wire fixing rod 42 ensures that the winding and fixing effect of the connecting wire is always reliable, preventing the connecting wire from becoming scattered or displaced during equipment operation or movement, and further ensuring the regularity of the line layout and the safety of the connection. The arc surface of the plug rod 45 is fixedly connected to two arc plates 47. The surface of the arc plate 47 is in contact with the irregular plate 41, which achieves the effect of preventing damage to the spring 46. This avoids the situation where the plug rod 45 slides too far in the single hole plate 44 when the staff pulls it, which would exceed the stress range of the spring 46, causing the spring 46 to lose its elasticity and become difficult to use normally.
[0029] Working principle: When the operator needs to use the water tank 301, firstly, the operator rotates the bolt 309 within the L-shaped plate 308 until the arc surface of the bolt 309 separates from the square plate 310. At this time, the torque of the torsion spring 311 drives the protective plate 307 to rotate at one end of the rotating rod 306 until the protective plate 307 is fully opened. Then, the operator can add an appropriate amount of coolant to the water tank 301. After the operator has finished using the water tank 301, the operator can rotate the protective plate 307 to move the absorbent pad 312, and the protective plate 307 will move the square plate 310. The plate 310 is moved until the surface of the absorption pad 312 is in contact with the water tank 301. Then, the operator can rotate the bolt 309 until the bolt 309 is inserted into the square plate 310. This achieves the effect of reducing the temperature of the exhaust fan body 1, preventing the exhaust fan body 1 from working for a long time. The temperature of the exhaust fan body 1 will continue to rise, and high temperature will affect the performance of the motor of the exhaust fan body 1. For example, the output power of the motor may decrease, resulting in insufficient smoke exhaust volume and air pressure, which cannot meet the design requirements of fire smoke exhaust and affect the smoke exhaust effect. This improves the practicality of the device.
[0030] When the operator needs to secure the connecting wires of the exhaust fan body 1, firstly, the operator pulls the insert rod 45 to move the arc plate 47. At this time, the spring 46 is stretched until the surface of the arc plate 47 is in contact with the single-hole plate 44. At this point, the arc surface of the insert rod 45 is completely separated from the irregular plate 41. Then, the operator pushes the securing rod 42 to slide within the irregular plate 41. After the securing rod 42 moves to the appropriate position, the operator can wrap the connecting wires of the exhaust fan body 1 around the arc surfaces of the two securing rods 42. Then, the operator can pull the securing rod 42 to slide within the irregular plate 41 until the exhaust fan body... The connecting wire of 1 is stretched, and then the staff can release the plug 45. At this time, the rebound force of the spring 46 drives the plug 45 to slide in the single hole plate 44 until the plug 45 is inserted into the irregular plate 41, which achieves the effect of wrapping and fixing the connecting wire of the exhaust fan body 1. This prevents the connecting wire of the exhaust fan body 1 from shaking and dragging at will due to lack of fixation during the movement of the exhaust fan body 1. This may cause the connecting wire to rub, hook or even pull frequently with the ground, other equipment or sharp objects, which can easily cause damage to the outer sheath of the connecting wire and breakage of the internal wire core, resulting in short circuit, leakage and other circuit faults, thus improving the reliability of the device.
[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
